Effect of natural gas temperature changes on combustion
Thread Content
During the normal operation of the boiler, due to weather conditions, the temperature of natural gas dropped from 10 degrees to 5 degrees. Will this have an impact on the boiler’s combustion? And will more natural gas be required to produce 1 ton of steam?
A preheater can be added before natural gas enters the furnace, which helps to save energy and reduce consumption.
You’re overthinking this. The specific heat capacity of gases is already low; a temperature difference of just 5 degrees has an effect that can be ignored~
When the temperature of natural gas is low, there is less water vapor present, so the proportion of natural gas increases; what do you think? Generally, water is separated first, followed by preheating.
Personally, I think the impact is minimal; if there is any impact, it is due to changes in temperature – the lower temperature of cold air required for gas, as well as heat loss from the furnace walls, play a significant role in that
